Tuesday February 12, 2013 Happening Now

North Korea has tested another nuclear device. This one apparently had twice the power of the nuke they tested in 2009. The North Koreans are also specifically threatening the United States, warning that it is just the beginning saying they have "second and third measures of greater intensity" in store. Russia and China have condemned the test, and are urging the North Koreans to return to six party talks. President Obama called it "highly provocative," and is demanding "swift and credible action by the international community." The U.N. Security Council holds an emergency session this morning.

The timing is surely no coincidence with President Obama set to deliver the State of the Union speech before a joint session of Congress tonight. Molly Henneberg, Shannon Bream, Ed Henry, and Jim Angle reporting on White House action today and the State of the Union including a side bar on Senator Marco Rubio who is set to give the GOP response.
